AUSTIN -- For the week ending May 28, feeder cattle price trends at Texas auctions were mixed, from $10 lower to $6 higher. Poor pasture conditions, tight supplies, lower fed cattle markets and fluctuating grain prices were again the primary influences on markets. Fed cattle prices were lower. Cotton prices were lower as export demand continues to falter. Corn and grain sorghum were higher because of continued planting delays in the eastern Corn Belt, while drought on the Great Plains and spring wheat planting delays pushed wheat prices higher. . . .
